Hi! Finally got around to trying this out, it's really cool!
I was wondering how the png sequences are exported in terms of quality? When importing for reference material, quality doesn't matter so much. But if I were to want it imported to exist in my scene, like the background in your dove example, how does it determine overall image quality? I ran a test exporting an image sequence from Silver vs Media Encoder's default PNG settings, and the Silver exports are about half the MB of the Media Encoder exports, and the image quality isn't as good as Media Encoder. So Silver wins on file size here, but not when needing high fidelity exports. That's not to say the image quality is unusable, I had to zoom in past 100% to see a significant difference, I'm just curious is all!
A couple other minor things I see that could improve this would be being able to change the size of the converter window, and maybe putting the compatible file types in the info box that pops up when hovering over the "Import Source Material" button. I wouldn't have known I could use gifs until I watched your explainer video.
Aside from that, it's honestly a really solid tool and I'm really excited to use it!
